thanks Bonus, that's exactly what I needed to know.
My goal is to pretty much replicate the white van at the start of this thread, down to the wheels which I think are 15" Compomotive ML's.
I'd planned to fit the arches, then measure from there back to the current hubs to see what size is possible.
I'm not certain what the diff is that's in it at the moment, haven't got that far.
I don't think it is anything special, the previous owner suggested  it might be a 2L Mk2 diff, as it has mounts for a sway bar. Looking at it though I thought it was less beefy than what is in my 4 door.
Will suss that out further.
 
I'll cut the wheel tub as suggested at the join, and pattern up an infill.
 
I recieved my panel delivery came yesterday, sills,floorpan and heater bubble. I expected they would need some tweking to fit, but did not expect they would be so rough. The floor pan had ripples in it where the stamping should have been flat, it looked like I made it. The heater bubble had been manually panel beated to get some dents out, and still needs work. And they were not painted like you see online, just left bare metal. 
Overall, if thats the quality of M*gnum Panels, im not too excited.
 

I dont know what happened to the last post anyhow, I'll retype.
yes they have Magnum stickers, but I have a Zebra thermal printer at work, and could bang those out in a few minutes.
Anyhow, see what you think. To me, just a bit dissapointing thats all.
 
 

Ouch, your ankle must be sore!
 
The van is coming along nicely, at least the floor panels you purchased will be hidden under the carpet.
 
The steel I use is just under 1mm, about .9, you may be able to get 1.2 and push your folders limits, it will be a bit easier to weld but harder to form. I only use a mig with gas for welding body panels, it's worth the money and you won't look back once you have tried it.

yes, I was lucky with the tetnus. We had a new addition to the family (not immediate family, although I would tomorrow, but the boss is getting a bit too old now ()), and before we could see the new bubs, we had to get an imunisation jab. Part of that, was Tentnus as well, so that was a bonus (sorry Bonus), done in 2018.
Hosing the tear out sounded fun Marty.
I havent looked at the jacking points yet, I'm trying to focus on one section (ok, 3 sections) at a time, or else i'm sure that i'll sit down at one stage and the reality will hit, as it will look like a total basketcase.
 
Currently:
-1 rear door stripped and sanded
-passenger door off
-passenger guard off and 1/2 stripped
-passenger inner sill and floor cut out (previous owner)
-driver floor and seat crossmember cut out (previous owner). I see what you mean Marty about floor pan tab.
-anywhere thats painted black on the bulkhead  is likely to be paint over no more gaps
Update: that window pictured above is now primed, and came up ok to me. It needs some high build and spot putty just to sharpen up the fold lines a little, but thats ok for now.
 
I welded up the antenna hole in the guard, just to do something, and have started to make corner panel infills for the front of the well. Problem is, the corners on both sides were already chopped out, so it's  guesswork as to how it should look. In my last trip to metalland I bought just some sheet offcuts, and bingo, there as some 1.2? Definitely harder to form, but the folder did ok actually. The best thing I learnt, the folder makes a great clamp just to hold steel why you cut it. Worth buying for that alone. My other find was the poly strip disks for the grinder, gee they do a great job. Sorry no pics, i'm meant to be doing something else, and will be off air for a week.
 
I got the bubble arches last night (they are Magnums ,and yes painted black as norm), just have to figure out which is which 
Mind you, none fit with the wheels on, the inner stamping flange needs trimming first.
The temptation is so great just to start hacking the rear 1/4 to get fitting, but the van needs more strengthening before I start cutting more bit out, so I have to wait....
 
I'm thinking I really might have to make a roll over jig though. I practically have 1/2 already with dads bus engine stand. welding the sills and inner arches would be much easier.
I emailed Compomotive Uk to see if they could identify roughly what the rear wheels were on the white bubble van. Mainly the offset or backspace. I know it probably impossable to tell from a pic, but I like the way the spokes look longer because of the disk. Wheel ocd. And I think the wheel color will be gold.
Just cant pic the van and stripe color. 
Time to move past orange.
Have a good week fellas. Keep your fingers and toes.
 
 
 
 

Just finding out what I missed after a month off the social media.
Congrats Deano on the Van, birthday and progress so far. Watching with interest...

some pics from weekend 4.
Inner and outer sills cut off.
Do the coupes have the stiffening box section also, or just vans?
Obligatory pic of the cut offs, and a huge file of good aussie dirt.
The folder got a good work out.

Are you sure they are compomotive and not performance but in a large spec? Im leaning towards 8-10inches wide

Im sure one of the fb pages would have the answer - the owner might even be able to be tracked down and give you the real details of them
